ROLL FOR PLAITING-MACHINES. A

SPECIFICATION forming part of" Letters Patent No. 701 ,841, dated June 10, 1902.

Application filed September 11, 1901. Serial No. 7 ,041. (No model.) I

To all whom, it may concern:

Be it known that I, DANIEL L. CHANDLER, of Ayer, in the county of Middle'sex'and State of Massachusetts, have invented certain new and useful Improvements in Yielding-Surfaced Rolls, of which the following is a specification.

This invention relates to rolls for use'in plaiting-machines and in other. situations where it is desirable to have an; even pressure on the work, although the latter may be uneven in contour.

The invention consists in the novel construction hereinafter described and claimed.

Of the accompanying drawings,Figure 1 represents a longitudinal section, partly broken away, of a sectional roll constructed in accordance with myinvention. Fig. 2 represents a transverse section on the line 2 2 of Fig. 1. Fig. 3 represents an-end elevation.

The same reference characters indicate the same parts in all the figures.

In the drawings, 1 is a central supporting shaft or arbor, and 2 2 are a series of rings or sections making up the cylindrical periphery of the roll and displaceable radially of the shaft 1 independently of each other, so that portions of the periphery of the roll may yield more than other portions to accommodate inequalities in the work. Between the shaft and rings is interposed a series of tangential spring-plates 3 3, whose inner margins con- I am enabled to obtain ample spring-pressure in a contracted space, thereby retaining a large diameter of shaft, which is essential to prevent springing or bowing in a long roll.

6 6 are fixed rings or flanges on the ends of the roll, between which and the end rings of the series 22 are interposed short helical springs 7 7, which exerta balanced axial pressure serving'to hold the rings 2 2 in contact. These rings 6 allow for longitudinal expansion ofthe roll periphery, which would otherwise cramp and. interfere with the relative radialmovement of the rings when the roll is subjected'to heat.

Ido not confine myself to the details of construction herein set forth.

1'. Arollcomprising a peripheral portion composed of a plurality of independently- 'ngovable annular sections, a supporting-shaft, and independent spring devices interposed between saidshaft and peripheral portion and each comprising a trunk portion and a plurality of spring-fingers integral therewith and bearing on a plurality of said sections, the said fingers extending substantially tangential to the shaft.

2. A roll comprising a peripheral portion composed of a plurality of independentlymovable annular sections, a supporting-shaft, independent spring devices interposed between said shaft and peripheral portion and each-comprising a plate extending longitudi nally of the shaft and having a plurality of integral spring-fingers bearingfupon a plurality of said sections and independent removable attaching devices detachably securing I .said plates to the shaft. stitute hub or trunk portions and are attached 3. A roll comprising a peripheral portion composed of a plurality of independentlymovable annular sections, and means yieldingly pressing said sections together in an axial direction and adapted to yield to permit their axial expansion.

In testimony whereof I have affixed mysignature in presence of two witnesses.

I DANIEL L. CHANDLER.
